With a lot of help from mates we installed the wings tonight ... thanks guys, from left to right in photo # 3: Willy, Jards, Gary, Geoff and Mike. Everything went pretty smoothly, so now I can crack on with measuring 1000 times, drilling the rear spars and then installing the flaps and ailerons, after which will come the wing root, gear leg and intersection fairings plus wheel spats. I should have put the aileron torque tubes in the wings beforehand, but they may just fit down the litening holes. If not I'll have to trim the torque tubes during final assembly ... sigh.
